I don't plan to have subforms correspond to tabs one-for-one, because there are multiple models, each with a corresponding subform. I just want to split up groups of fields into tabs for the sake of presentation; there's a single submit button for all. When they move from tab to tab they aren't going to be submitting, but it seems a fine opportunity to processAjax() and validate the current section of the form before it gets hidden from view. -- Support real health care reform: http://phimg.org/ -- David Mintz http://davidmintz.org/
